NORTH PERTH, Australia — Hartshead Resources has contracted GEOxyz UK to conduct a geophysical survey over the Anning and Somerville gas fields and proposed inter-field pipeline locations in the UK southern North Sea.
GEOxyz will likely mobilize the DP2 survey vessel Geo Ocean III for the campaign in April. The vessel provides deep-push cone penetration testing (CPT) and vibro-coring capabilities.
Hartshead is seeking an interpretation of the seabed geomechanical and engineering conditions at the field locations and an environmental baseline survey and habitat assessment.
The program will comprise a detailed analogue and 2D high-resolution survey over a 1,000 x 1,000 sq m box area centered on the planned jacket locations; a more detailed 400 x 400-m analogue survey supporting placement of the jackets; mini-CPT and vibrocorer sampling at 1,000 me intervals of the inter-field pipeline route between the two jacket locations, for geomechanical and geo-environmental seabed characterization; and onshore and offshore laboratory testing of seabed samples taken during the sampling operations.
Hartshead will incorporate the results into the environmental statement for submission of the field development plan later this year as well as the platform FEED jacket design verification.
Hartshead CEO Chris Lewis said, “The Phase I development is progressing well, with work across platforms, pipelines, wells and offtake moving forward.”
